1. A transmission apparatus for an agricultural vehicle, comprising:
a leading transmission part which shifts power transmitted from an engine of an agricultural vehicle;
a clutch part connected to the leading transmission part to selectively output power transmitted from the leading transmission part;
an adjustment part connected to the clutch part; and
a following transmission part connected to the adjustment part to shift power transmitted from the adjustment part,
wherein the leading transmission part includes a first leading transmission unit which shifts the power transmitted from the engine and a second leading transmission unit which shifts the power transmitted from the engine,
the clutch part includes a first clutch unit connected to the first leading transmission unit to selectively output power transmitted from the first leading transmission unit and a second clutch unit connected to the second leading transmission unit to selectively output power transmitted from the second leading transmission unit,
the adjustment part includes a first adjustment unit connected to the first clutch unit, a second adjustment unit connected to the second clutch unit, and an integration unit connected to both the first adjustment unit and the second adjustment unit, and
the following transmission part includes one following transmission unit connected to the integration unit
wherein the first adjustment unit includes a first adjustment gear rotated by power transmitted from the first clutch unit;
the second adjustment unit includes a second adjustment gear rotated by power transmitted from the second clutch unit; and
the integration unit includes:
a first integration gear engaged with the first adjustment gear to shift power at a first gear ratio;
a second integration gear engaged with the second adjustment gear to shift power at a second gear ratio; and
an integration shaft to which the first integration gear and the second integration gear are coupled and which is rotated by power transmitted from any one of the first integration gear and the second integration gear,
wherein a first diameter value which is a sum of a diameter of the first adjustment gear and a diameter of the first integration gear and a second diameter value which is a sum of a diameter of the second adjustment gear and a diameter of the second integration gear are the same,
wherein the first integration gear is engaged with the first adjustment gear, and the first integration gear is not engaged with the second adjustment unit;
the second integration gear is engaged with the second adjustment gear, and the second integration gear is not engaged with the first adjustment unit;
when the first clutch unit operates to output power, the power, which is shifted while the power is transferred through the first adjustment gear and the first integration gear, is transmitted to the following transmission part through the integration shaft, and
when the second clutch unit operates to output power, the power, which is shifted while the power is transmitted through the second adjustment gear and the second integration gear, is transmitted to the following transmission part through the integration shaft.
